Reaction Steps

EDCI (7.07 g, 36.9 mmol) was added in one portion to a stirred solution of 3-Iodo-5-nitro-benzoic acid (2.31 g, 24.6 mmol), HOBt (4.985 g, 36.9 mmol), 2-Amino-1-methoxypropane (2.73 ml, 24.6 mmol) and NMP (4.06 ml 36.9 mmol) in CH2Cl2 (120 ml) and DMF (10 ml) at 0° C. The reaction was allowed to warm to room temperature and was stirred over night. The reaction mixture was then washed with 2N NaOH, water, brine, and dried over Na2SO4. Solvent was removed in vacuo to give 2.50 g of 3-Iodo-N-(2-methoxy-1-methyl-ethyl)-5-nitro-benzamide as a yellow solid, MS (M+H)=365. This material was used without further purification.
